Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed September 11, 1915. Serial No. 50,145.

To all whom it may concern:

Be it known that I, EUGENE W. WALSH, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Doors, of which the following is a specification.

This invention relates to improvements'in doors and particularly to that type of doors which are adapted to fold into small compass.

One of the objects of the invention is to provide a door capable of being easily and noiselessly operated by a light pressure applied in the desired direction, without clanger of pinching the person or garments of an operator.

A second object is to provide a door that is substantially sound-proof by reason of its overlapping side elements, and finally to provide a door of neat appearance, strong yet light, and relatively inexpensive in its construction.

These and similar objects, which will be- 7 come morefully apparent as the description progresses, are attained by the novel structure herein set forth and shown in the annexed drawing which forms part of the disclosure.

In the drawing :Figure 1 is a front elevation of a door made in accordance with the invention. Fig. 2 is an enlarged transverse sectional view, taken on line 22 of Fig. 1. Fig. 3 is a similar view of the same, showing the door elements in a folded position. Fig. 4 is a further enlarged fractional front view, and Fig. 5 is a plan view of an element used in connection with the center joint rod.

The drawings illustrate the application of a door to a narrow chamber or room, such for instance as a telephone booth, where it is desirable to have a door that can be quickly-operated, both in opening and closing, without noise, jar or vibration, that will stay in the position in which it is placed and which, when folded or opened, occupies a minimum of space.

Referring to the drawing, the side walls of the chamber are indicated by the numerals 10 and 11, respectively right and left, to which the front walls 12 and 13 are joined as shown, and it will be evident that these with panels 16 and 17 of glass if preferred.

The stile 18 of the door element 14 has on its outer side a flange 19, overhanging the jamb 12 when the door is closed, on the opposite side of the stile 18 are hinges 20, the

joint 21 of which is set back from the edge so as to permitthe flange 19 to swing past the corner of the door jamb. Between the hinges is a longitudinal cleat 22 secured to the inner side of the stile 18 in such manner as to completely cover the joint opening between the stile and jamb when the door is closed, thus affording a double protection against the transmission of sound. 1

The opposite stile 23 has a beveled recess 2& extending its full length, terminatinglaterally in a beading 25 and the stile 26, of the adjoining door element 15, has a similar beveled recess 27 and head 28. To these beveled surfaces are attached the straps 30 of the connecting hinges, the pivot joint 31 of which is substantially in the vertical plane of the front of the doors.

" The-front stile 32 0f the door element 15 has a bevel 33 formed on its outer edge to suit the shape of the jamb 13 and is also formed with an extending flange- 3 1 adapt-- ed, when the door is closed, to make contact with the jamb; further protection against the passage of sound is provided by the cleat 35 secured to the inner side of the jamb 13. In order to cause the door to properly operate in a predetermined path, a radius rod is pivoted within the room or booth, the front end 38 of the rod being pivoted to a bracket 39, secured at the inner side of the door element 15 near the top.

'It is to be noticed that the narrow adjacent edges of the stiles 23 and 26 are formed concavely to a radius coincident of the hinge joints 31; this radius extends the full length of both stiles and has suited to it rods of appropriate length to fill the space between the hinges and also at the top and bottom of the door, the rods being of the same diameter as the hinge joint. In place of the usual pin at these joints, special pins 41 are used the same being extended at both ends beyond the hinges and entered into the rods 40 as shown thereby holding them in register, close to, but clear of the stiles.

AL further guiding means for the rods is provided in the plates 42- secured to the top and bottom of the door upon each of its elements and having an opening 43 to receive a pintle formed with the corresponding ends of the extreme rods. Thus the rods are arranged to close the opening otherwise existing between the door sections notwithstanding the position the sections may be in, effectually preventing the issuance of sound or the possibility of engaging the clothing or fingers in the opening.

In operation, when the door is closed, as shown in Fig. 2, pressure may be applied to the elements 28, 26 or 4:0, whereupon these parts move back or inwardly, turning on the hinges 31; this causes the door element 14 to'swing upon the hinges 21 and at the same time the stile 32 is moved forward or outward as the door element 15 cannot move back but is caused to pivot at the point 39. This action continues until the door elements fold together, the rod 38 at that time swinging toward the right until the parts come into the position shown in Fig. 3.

Pressure applied from the interior against the rod 40 or from the outside against the stile 82 causes the door to close.

The entire absence of rollers, wheels, trackways, etc., eliminates the noise which is otherwise created and it will be evident that the movement is smooth and easy. Also that when the door is closed that there exists at each edge a double means for preventing the transmission of sound, besides that at the center. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

' 1. In a door, the combination with a pair of folding elements each beveled at the joint on the inner side thereof, of cylindrical joint hinges having leaves attached to the beveled edges of said elements, the cylindrical portion of each of said hinges being disposed in the plane of the front of said door elements, piv0t pins carried by said hinges and extending therefrom, cylindrical joint rods registering with and forming 'continuations of the cylindrical portion of said hinges, said rods being separate from the door elements and filling the unoccupied spaces along the edges thereof.

2.. A folding door comprising two main elements, one being hinged to a door jamb,

the other having anedge mating the oppoand means combined with the hinges whereby the oint between sald door elements is covered.

In testimony whereof I have signed my name to this specification.
